SEPTIMUS HA'SLAM, JR, OF NEW BRITAIN; CONNECTICUT, ASSIGNORTO HIMSELF AND JOHN -B. TALGOTTL Letters Patent No. 80,283, dated July '28, 1868.'

IMPROVEMENT IN MACHINE FOR PRODUCING A REGIPROGATING MOTION IN KNITTING- MACHINES, dro- 'To ALL WHOM IT MAY CONCERN: I

I Be it known that I, SEPTIMUS HASLAM, J r., of New Britain, county of Hartford, and S'tat eof Connecticut,

havejnvented certain new and useful Improvements in Drawing a Cross-Motion for Knitting-Machines, lopm or other machines, to which it may be applicable; and to enable others skilled in the art to malie and use the same,

Iwill proceed to describe its construction and operation by refefi'iiig to the drawings, in which the same letters indicate like parts in each of the figures.

The nature of this invention will be understood from the specification and drawings.

' The object desired to be attained thereby is to provide a self-acting reciprocating motion,"which.shall be positive in its action, and not lidh le to get out of order, and which maybe suspended ntinterims,when necessary,-

This machine may he applicd to; knitting-machines now in use, known as straight-knitting machines.

It is to he understood that this device is an independent machine, and can be used with any of thestraightknitting machines as an attachment.

In the accompanying drawings-:-

Figure 1 is a side elevation.

Figure 2 is a view of a portion of-the opposite side.

Figure 3 is a sectionalv view of the clutch or change-motion.

Figure 4 is a view showing the construction of the metal chain and flange-gea'iyby means of'yvhich I are enabled to keep the traveisemotion or slur-cock always in its proper placev and position, and to secure a positive action thereof in harmony with its relative pa'rts and here I wish to state that fertile purpose of showing the'device in a compact form, I have arranged the flange-wheell at theright hand, but when put in use, th'e wheel 2, with the slur-cock her a, will he placediin a line witlr and upon the opposite side or direction of the wheel 1, and at the proper or desired distance therefrom, o vice versa, as occasion requires for a right or left-j hand machine.

a is "the framework of this attachment.

b is a driving-shaft, "which takes its bearings in the framework 0 is a crank or pulley, for imparting motion to said shaft. (1 is a sleeve, fitted closely and workingfreely uponthe shaft 6. his a clutch, fitted closely and working freely in a lateraldir'ecjtion with and upon the sleeve d, and is. held from revolving, except with the sleeve, hy a spline, not shown. I v

ff areTbevel-gears, fitted closely and revolving Tfreely upon the sleeve d, one at eaeh end of the clutcn. :4. These gears are. provided with vgrooves, in which are secured clutch-pins, g, and the clutch is provided with clutch-pins g"; These pins are so arranged thatwh-en the clutch moves back and forth between the gear-wheels ff, the pins y will strike fi'rst ope and then the other of the pins 9, thus causing a reverse or change-motion of the flange-wheels or gears 1 and 2 through the gears 3 4 5.

h is a collar, for-holding the genrfin its proper plaoe'relativeiy to the gear 3. .i is a collar secured to the shaftb by a pin or screw, j, which, with the intermediate collar. It, holds the gearf' in its relative position to the gear 3. This collar is is made or secured on the end of the sleeve d, and in its face is formed a gro'ove,,in which are secured oneor more pins, Z.

m is a collar in which are securediclutch-pins, l. These pins project and .p strike the pins l in the collar is. l

This collar. m is also provided with a smaller side-collar, opening of the shipper-lever n by screws or pins, 0. v a is a spring, arranged on the shaft b, and whic alent, and presses against the end of the collar m, to keep the pins 0 7c,on the sleeve ll, carrying the clutch. I

15 through the collar and which works in and is secured to the sides of the h takes itsbe'arings against thc framework, or its equivf the collar in connection with the collar structed.

Ifthe shipper be pressed back, the motion of the device will suspend the action of the drawing-across motion during one or more revolutions of the shaft 6, and while the narrowing operation is being performed, after which thespring o is allowed to throw said collar mhack into connection with the collar is, which imparts motion to the hole machine. v

p is a shipper,'one end of whichis secured upon a stud, o", and the other end vibrates between guards,

, q is a'strike-platc, secured upon thc vibrating shipper-bar p, the ends of which extend each way nearly to the gears ff, so that the pins or cams r, on the inner sides of the gears, will strike alternately the ends of the plate 9, and press the shippenundcr the v-sh'aped projection formed on the spring 8, where it will be held until again moved by thecam r. 4 I

u is a gear, made to correspondwith the half-circle link-chain gear.

v is a half-circle link-chain, united by pins through the centre line of the half circle, thus forming a perfect unyielding gear.

Thus it will be seen that I produce in every part a sure, unyielding, and positive motion, and thereby secure more and better work,

In the old kind of draw-motion, whenever iti'ails to do its part, (and that is quite frequently,) a hole vould bcmade in the cloth or web, or it would be pressed oil the needles, and it not only would take considerable.

time toppt it on again, but it would'not be-made as perfect as it the machine had continued its work unob- I believe I have thus shown the-nature, construction, and advantage of this invention, so as to enable others skilled in the art to make and use the same therefrom;

What I claim, therefore, and desire to secure byLetters Patent, is-- 1. The combination, with the shaft b, of the sleeve 02, carrying the clutch and Wheels ff, and the collar Ir, and collar 2', on the shaft, and clutch m, or its equivalent, substantially as described.

2. The gears ff, arranged upon the sleeve 1, in combination with the clutch a, plate q, upon the shipper p, and spring 8, or their mechanical equivalents, with the gears 34 5 1, and chain 1', for the purpose substantially as described.
